This paper presents a method for urban resilience quantification from the energy metabolism perspective, taking into account different sustainability dimensions and introducing such aspects as environmental, social, economic, technical and risk aspects. The aim is to develop a methodology for resilience index quantification for urban thermal energy system taking into account different levels of urban energy metabolism - production, supply and use, and approbate it on the real Latvian, Lithuanian and Estonian cities examples. The proposed approach includes a set of indicators to be used within the scope of thermal energy metabolism. The analysis is supposed to end with identification of the “weak points” of each studied energy system in order to help stakeholders develop the strategy for resilience enhancement in future.
